The are three main types of methods used in jqGrid:

• Standard jqGrid methods which can be jQuery methods too. The methods can be used like $("#grid").jqGrid("setHeight", 200); or like $("#grid").setHeight(200);
• DOM Extensions. The methods can be used like $("#grid")[0].triggerToolbar();
• Static methods, which are extensions of $.jgrid or $.fmatter object. An example of usage looks like $.jgrid.jqID(id) or $.fmatter.NumberFormat(num, format). Some from the static methods need be called with this initialied to the DOM of the grid. For example, var $td = $.jgrid.getDataFieldOfCell.call($("#grid")[0], tr, iCol);
